I need someone who can make all Windows TPM 2.0 remote attestation checks pass inside a Linux KVM/QEMU Windows VM. I don't care how it is implemented. I just need a working setup where everything passes, including: Trusted vendor EK/EKCert EK certificate verification EK public key matching the certificate AIK enrollment and trust Isolated VM PCR domain TCG Event Log PcrsMatchTcgLog=true PCR replay / all PCRs matching TPM Quote verification Nonce verification Credential Activation Microsoft/external EK verification Windows TPM pre-attestation / health checks Current setups only give me part of this: physical TPM passthrough gives trusted EK/EKCert but causes PCR/TCG log mismatch, while software vTPM gives clean isolated PCRs but uses an untrusted/operator EK certificate....

I’m looking for an experienced personal-protection professional to accompany a well-known celebrity through a varied schedule of public events, private residences and frequent national and international travel. The role goes beyond standing at a distance; I want someone who can offer discreet yet friendly and engaging support—reading a room, diffusing attention with a smile when it helps, and switching instantly to a firm protective stance when it doesn’t. Day-to-day you will: • Shadow the client from pick-up to drop-off, maintaining clear, proactive situational awareness. • Liaise with venue security teams, hotel staff and travel coordinators to close any gaps before we arrive. • Handle crowd control, secure private areas, and coordinate safe vehicle ...

I need a clean, repeatable OAuth2 login flow that lets my application connect to both the Athena Healthcare FHIR sandbox and a live customer instance without changing code between environments. The login must operate strictly system-to-system—no individual user roles—yet obtain tokens that carry full read/write scope for any valid FHIR resource exposed by Athena. You will handle the entire authentication layer: client registration (sandbox and production), token retrieval, automatic refresh, and secure storage of secrets. I should be able to point the code at either endpoint, supply the relevant client credentials, and immediately receive a working access token that passes Athena’s FHIR authorization checks. Deliverables • Source code for the OAuth2 client (...

I need to enhance my current software application and will share the full technical brief once NDA and repository access are arranged. The codebase is stable but lacks several features and performance optimisations that have become critical for the next release cycle. Key objectives include: • Analyse the existing architecture, pinpoint bottlenecks, and recommend a clear upgrade path. • Implement the agreed-upon feature set, adhering to clean-code principles and existing style guidelines. • Refactor legacy modules where necessary to improve speed, security, and maintainability. • Write concise inline documentation and an update log so future contributors can ramp up quickly. • Deliver unit and integration tests that prove each enhancement works across ...

I need a brand-new personal Gmail account created from scratch and configured exactly to my requirements. Once the address is registered, you will secure it with two-factor authentication, add my recovery phone and backup email, and walk me through any verification steps that require my direct input. Because this is a personal account, no data migration is involved. What I do need is a clean, ready-to-use inbox with a few sensible defaults—basic filters for spam, a primary label structure, and an uncluttered interface (chat and Meet toggled off). Please document every setting you change so I can review and adjust later if needed. Deliverables • Live, functioning Gmail personal account created under the name I provide • Security and recovery options fully enabled and v...

I need a complete teleradiology website live in 2–3 days. My primary aim is to grow the business, so every element should help me attract new customers, increase brand awareness, and drive sales and revenue. To achieve that, the site must let users upload and share imaging files securely, open a direct channel for patient-doctor communication, and produce clear diagnosis reports that can be viewed, downloaded, or emailed. The experience has to be fast, fully responsive, and search-engine friendly so I can start paid campaigns the moment we launch. Security and privacy are non-negotiable; please be ready to implement encryption and the standard protections expected for medical data. A clean, modern look that reinforces trust in the brand is equally important. Deliverables • ...

I’m compiling a knowledge pack on Web3 with an emphasis on blockchain technology, and the section still missing is a deep-dive into scalability. I want a clear, beginner-friendly yet technically accurate overview of today’s scalability approaches and how they intersect with Delegated Proof of Stake (DPoS) networks. Your task • Explain the core scalability challenges—throughput, latency, storage growth, and network bandwidth—in plain language. • Describe the main strategies used to overcome them (layer-1 optimisations, sharding, sidechains, roll-ups, etc.), then relate each strategy to DPoS systems such as EOS, TRON, or BNB Chain. • Detail how validator delegation, block production scheduling, and incentive design in DPoS influence performance a...

I run an e-commerce site that is ready to launch, but I still need a seamless, fully secure payment solution put in place. Your task is to wire the store to a trusted gateway—whether that ends up being Stripe, PayPal, Square, or another PCI-compliant API that you recommend—so customers can check out without a hitch. Here is what I expect: • End-to-end gateway configuration on both the front end and server side • API keys, webhooks, and callback URLs set up and verified in test and live modes • Responsive error handling and clear status messaging for the shopper • Final sandbox and live transactions fully tested, with screenshots or logs as proof • A brief hand-off guide so I can manage refunds, captures, and future updates on my own My prior...
